facebookios
I'm using an iPhone 7 running iOS 12.
When I'm in an on-going video chat, I can't find the "add people" button to add more people to the on-going video chat. In Android I can see that button just fine, so I'm surprised that iOS doesn't have it.
Do I need to activate it via settings or something?
Turns out I was wrong; you can configure this on iPhone.
As the guide on this page taught me:
Now, in my case it was probably Nearby Friends that I mostly wanted to disable. I ended up turning off some others too:
I had this exact same problem (I'm on an iPhone 5) and just fixed it. I connected Waze to my Facebook account - setting my privacy level at 'My Facebook Friends' - and then went into Settings > Facebook > 'Update Contacts.' That took a few seconds, but when I went back to Waze all my Facebook friends had magically appeared. Hope that helps.

I got it. It's not the iPhone's fault, it's the fault of the other phone which uses Messenger Lite. Messenger Lite doesn't have conference call feature (at this moment). So if Messenger (full version) calls Messenger Lite, the "add people" button isn't available. So I install Messenger (full version) for the other phone and try calling again, and now I can see the "add people" button.
